Abstract

"SISTEMA DE RáDIODIFUSãO DIGITAL, TRANSMISSOR DE RADIODIFUSãO DIGITAL, RECEPTOR DE RáDIODIFUSãO DIGITAL, E, MéTODO DE RADIODIFUSãO DIGITAL". Em radiodifusão digital terrestre, na qual uma corrente de transporte de Sistemas MPEG-2 é modulada OFDM, correntes de transporte a serem transmitidas conectadas são agrupadas e são correlacionadas. Uma estação de radiodifusão cria um descritor de transmissão conectada para relacionar as correntes de transporte a serem transmitidas conectadas, escreve o descritor de transmissão conectada criado em uma NIT e multiplexa um sinal para uma corrente de transporte.
